CAR-VENTILATOR.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed November 19, 1917. Serial No. 202,791.

To all whom it may concern:

Be it known that 1, WILLIAM E. WINE, a citizen of the United States,residing at T- ledo, in the county of Lucas'and the State of Ohio, haveinvented new and useful Improvements in Car-Ventilators, of whichthefollowing is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

My invention relates to new and useful improvements in ventilators forfreight cars and to that type of ventilator shown in patent granted meOctober 1st, 1912, bearing Serial Number 1,040,084.

The object of my invention is to provide a ventilator that incorporatesall the advantages of my previous ventilator and with a furtheradditional advantage of having tighter sealing joints.

lVith these and other objects hereinafter explained in view, myinvention cons sts in the construction and combination of ele- Inentshereinafter described and claimed.

' closed position; Fig. 3 is a partial section on line 2-2 showing theshutters open; Fig. 4 shows a modification, in part, similar to Fig. 2;Fig. 5 shows still another modification; Fig. 6 is a section on line 66of Fig. 2; Fig. 7 is a section on line 7-7 of Fig. 5; Fi 8 is a sectionon line 8--8 of Fig. 4.

imilar characters designate similar parts throughout the several figuresof the draw- 1n s.

eferring now to the parts by number:

The frame is composed of sides 1, top bar 2 and bottom bar 3. Theopening between the sides and top and bottom bar is opened and closed byshutters which are operated by operating bar 5. The operating bar 5 isconnected to shutters 4 by means of lugs 6 and pins 7. The shutters 4are pivoted on trunnions 8 in pockets 9 located on sides 1 tothe frame.The shutters 4 are provided along their upper edge with a rib 10 whichextends vertically above the bottom edge 11 of the shutter immediatelyabove, when closed.

The sides 1 are provided with sealing ribs 12 which are parallel to theinner surface of the shutters 4. The shatters 4 are provided with arms13 to which are attached the trunnions 8. The arms 13 are also providedwith sealing ribs 14 which are parallel to the inner surface of ribs 12.

The top bar 2 of the frame is provided with a depending rib 15 which isadapted to engage rib 10 on the top shutter. The bottom bar 3 isprovided with an upwardly extending portion adapted to engage the bottomedge 11 of the bottom shutter. The bottom bar 3 is also provided with amember 16 extending horizontally therefrom for engagement with thelocking bar 17. The locking bar 17 is provided with a slot 18 in its topend and a slot 19 in its bottom end for the purpose of engaging themember 16 when the shutters are in their closed and opened positionsrespectively.

This locking bar 17 is pivoted to connecting bar 5 by pin 20, and isprovided with holes 21 and 21 which gage with a hole 22 in the member 16when the shutters are in their closed and opened positions respectively.

It will thus be seen that in order to open the shutters from theirpositions as shown in Fig. 2 to their position shown in Fig. 3, it isnecessary to revolve the bottom end of the locking bar 17 upwardly intoa horizontal position until the upper slot 18 disengages the member 16on bottom bar 3. Then the shutters can be revolved to their opendownwardly to the vertical position shown in Fig. 3 with the slot 19engaging the member 16 and hole 21 gaging with hole 22 ready for theirreception of any suitable locking'or sealing device.

In the modification shown in Figs. 5 and 7, the shutters 4' are almostidentical with the shutters shown in Fig. 2, the only difference beingthe elimination of trunnions 8, the sealing rib 12' serving as a guidefor the shutter.

The modification shown in Figs. 4 and 8 is an obvious 'eYfpedieiit, itbeing only a transosition of elements from that shown in Fig. 5, theribs23 and 24 being located on the sides of the frame and incloses theends of the shutters for guiding them into their opened and closedpositions.

By eliminating the trunnions 8 it is possible to use intermediatemembers 25 between the sides which add materially to the strength of theframe. These intermediate members 25 can be made of any convenientshape.

It Will be understood from this description that although theimprovements in this invention are simple, they accomplish in athoroughly practical manner all the objects sought.

ll Wish it further understood that I do not desire to be limited to thespecific construction or arrangement of elements shown and described, asit is obvious that changes in construction and arrangement may be madeWithout departing from the spirit of the invention.

Having thus described my invention, 1 aim in the appended claims tocover all modifications Which do not involve a departure from its spiritand scope.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is:

1. A Ventilator comprising a frame member, a plurality of shuttermembers operable in said frame member and moving in an arcuate path, aplurality of guiding and sealing ribs on one of said members so that,counting shutter, three thicknesses of metal at the ends of each shutterare disposed between the inner and outer sides of the ventilator.

2. A ventilator comprising a frame member, a plurality-of shuttermembers mounted in said frame member and moving in an arcuate path, aplurality of sealing and guiding ribs on one of said members, said ribsters mounted in said frame and adapted to move in an arcuate path, anarcuate rib disposed opposite the ends of each shutter and twoarcuateribs formed on the sides of each shutter to inclose the 'rib onthe frame to thereby accurately guide each shutter in its movement andpresent a double sealing ac tion to the edge of the shutter, and meansfor operating the shutters simultaneously;

4. A ventilator comprising a frame, arcuate shutters mounted in saidframe and operable in an arcuate path, guiding means mounted on saidframe and guiding means formed on said shutters at their sides tocooperate With the said first-mentioned guiding means, said guidingmeans on both the frame and on the shutters also forming a double sealfor the shutters at their ends, means for operating the shutters andmeans for holding the said shutters in their open and closed position.

This specification signed and. witnessed this 17th day November, 1917.
